Specification af Letters Patent.

` Patented Dec. 1, 1908 Application led February 19, 1907. Serial No.358,307.

To all whom it may concern: I

Be it known that I, JOHN FREDERICK ZAPF,

a citizen of the United States,'and resident of St. Louis, Missouri,have invented certain new .and useful Improvements in rluing-Machines,of which the following 1s a specification.

This invention relates to improvements in gluing machines' and consistsof the novel arrangement, construction and combinations of parts as willbe -fully hereinafter 'described and claimed.

The object oI this invention-is to con-4 struct a machine whereby glueor paste is applied -to'the entire face or surface -of a sheet of paperor .cardboard to which is applkied covers as used in bookbinding and theA further object of my invention is to provide a machine having` anadjustable means to accommodate the insertion of any thickness of paperor cardboard and to apply glue or paste to the entire surface lof thematerial.

In the drawings-Figure 1 isa top plan view of my complete inventlon.Fig. 2 is an end view of the same looking from Vthe left. Fig.v 3 is anend View of the same looking from the right. Fig. 4 is a vertical,central, cross-sectional view taken on the line 4 4 or Fig. 1. Fig. 5 isa detail, perspective view of a portion of the adjusting mechanism withparts thereof broken away, showing its construction. Fig. 6 is a detail,perspective view of one ofthe guidepaWls made use of'to guide the paperor cardboard from the roller. Fig'. 7 is an enlarged, detail, sectionalview of a portion of the j gluing mechanism showing its .connection andmode ofoperation. Fig. 8 is a plan view of a modied form of gluing diskswhich may be applied to the shaft. Fig. 9

. is an end view of the same. A

In the construction of my invention I pro- .vide a vat 10 mounted uponsuitable legs or supports 11 and to one side of the Vat I apply anindicator 12 by whichl the amount of water contained within the vat isdesignated. Beneath the vat' I may vapply any -suitable heating devlceby which the water contained Within the vat may be heated.

Upon the vat and extending partly into the same I provide a basin 13 inwhich the paste or glue is retainedfand the same is neld in position byprojectlng'lugs 14 and with the disks.

15, the lug 14 being higher than the lug 15 so as to provide a tilt orinclined pitch to the basin so as to retain most of the paste or glue inthe rear end of the basin. The or paste within the basin is kept inproper condition by the heated water within the vat.

Upon the vat I mount the gluing mechanism which consists of a pair ofside walls 16 and 17.through which extends an operating shaft 18 andoperates in bearings, the lower portion of said bearings being formed bythe projecting `lug 19 which is integral with the walls 16 and 17, andthe upper portion V20 of said bearings being adjustable and secured tothe side walls 16 and 17 by screws 21 or the like. `In order that theshaft may be removed from the end walls I slot4 the same as indicated bythe numeral 22.

' Upon one end of the shaft 18 Iprovide a set of tight and loose pulleys23 and 24 by which said shaft is revolved when power is to be used, andupon said shaft-I. also provide a gear-wheel 25 which meshes withagear-pinion 26 mounted upon a shaft 27. The said shaft 27 is providedwitha plulue'- rality of feeding-disks 28 which are arranged 4 revolublymounted upon the shaft 18., The

shaft 27 is mounted in adjustable bearings 30 and is held and guided ininclined brackets 31 formed integral with the end walls 16 and 17Extending from Wall to wall is a rod 32 and on its projecting ends arelocated pawls 33, its free end provided with an inwardly projectingportion 34 which comes in contact with the under surface of theadjustable bearings 30. and the same is held in its ad-4 justed positionby means of the spring-lever 35 connected to one end of the rod 32, theother end formed into a handle 36, and when raised position the saidlever is brought in contact with the under4 surface of the projectinglug 37 formed on the endwall 17.

rBetween the inclined brackets 31 and resting upon the upper surface ofthe bearings 30 is a wiper casing -38 in which is placed a strip of:felt or other suitable material 39 and contacts with the edge of theseveral vit is desired to keep the feeding-disks in f feeding-disks to.wipe the surplus glue orV paste which may by chance come in contactshaped as indicated by the numeral 40, and in the same is provided aplurality of openin s 41 through which moisture may be applied to thewiping material as well as to act as air escapes when the material isplaced in position Within the casing 39. In' order to retain the wiperin close contact with the feeding-disk, I rovide arms 42 pivotallyconnected at their one end to onel of the inclined brackets 3l at thepoint indicated by the numeral 43, and the other end of the arms 42 isprovided with pins 44 to which is fastened one end of the springs 45,and the other ends of the said springs are held to the walls by means ofthe pins or screws 46.

The rear ends of the walls 16 and 17 are provided with recesses 47 inwhich is supported a rod 48, and on said rod are placed a plurality ofguide-pawls 49, the said pawls are loosely mounted uponsaid rod so thatthe same may be adjusted laterally as found desirable and their ends 50are brought in contact with the periphery of the roller 29 (see Fig. 4).The upper surface of each of the pawls is'suitably curved so as to guidethe strip of material and remove it from the surface of the roller. Theend walls 16 and 17 are also provided with upwardly projecting integralarms 51 to which is supported a rod 52, the ends of said rod rojectingthrough the arms and is provided with thumb-nuts 53 by which said rodmay be rigidly locked in position. Upon said rod are placed a pluralityof guide-bars 54 and to the rear end of said ide-bars is fastened a tubeor rod 55; the o ject of this device is to accommodate the variousthicknesses of material to be passed over the roller 29, and by means ofthe thumb-nuts 53 the device can be adjusted to bring the tube 55 incontact with the material to retain the same i against the roller, asshown by dotted lines in Fig. 4. When it is desired to apply the pasteor glue to a sheet of stiff cardboard, the device is then placed inhorizontal position as shown by dotted lines in Fig. 4, which will Ithenpermit the sheet of material to pass of its periphery glue containedwithin the basin, and in oron a straight line over the roller.

The glue or paste is applied to the sheet of material by means of theroller 29, a portion being subinerged into the der to prevent too muchof the glue yfrom coming in contact'with the sheet, I provide a scraper56 which consists of a skeleton frame supported upon lugs 57 carried bythe end walls 16 and 17, and the said scraper is held in adjustedposition by means of adjusting screws 57, the said screws operating inthreaded bores formed in the lugs 58 of the scraper and are operated bythe thumbnuts 59. The said screws are also provided with washers 60which retain vsaid screws in position within the lugs 6l formed on theend-walls 16 and 17.

In instances where power is not available, I may apply, as shown bydotted lines in Fig. 1, a handle 62 by which the roller may be operated.

In some instances where it is desired to apply glue or paste to thematerial in ridges or in spots, I provide the shaft 18 with disks 63 andspurs 64, as shown in Figs. 8 and 9.

- Upon the rod 32, and lugs 65 secured to the end walls I provide atable 66 upon which the sheets of material are laid to be fed over theroller, as shown by the dotted lines in Fig. 4.

Having fully described my invention, what I claim is:

1. A gluing machine comprising a basin, a roller extending throughoutthe length of said basin, and revolubly mounted on the ends thereof,feedingdisks adjustably mounted above the roller, a spring actuatedwiper located above the feeding-disks and a plurality of awls forremovin the material to be glued rom the roller, su stantially asspecified.
